Other mistake: Near the end of the picture Al is racing to the airport and the toys give chase in the pizza truck. Spud jams the transmission into gear without using the clutch. (Hey, it's only a cartoon and Goyozas had great transmissions). The entire chase, however, would have been in first gear, but the engine runs at a normal speed. The truck bounces to a stop at the airport and then the engine stops. If they weren't using the clutch the truck and the engine would have stopped (stalled-out) at the same time.
Other mistake: In the last scene with the baggage plane, Woody, Buzz, etc. are all near the plane when it takes off. Since they were following a big jet, they are well down the runway once it takes off. Later, without them backtracking the runway, another plane passes overhead very close, as if to land. There is no chance to land a plane if it touches down that far down the runway. You will not be able to stop in time.
